Hi Tony,

So my guess would be there're more than one syscon dts nodes named "scm_conf@0".
For omap5 and scm_conf@0, should be these 2: https://elixir.bootlin.com/linux/latest/source/arch/arm/boot/dts/omap5.dtsi#L167 scm_conf: scm_conf@0 { compatible = "syscon";
https://elixir.bootlin.com/linux/latest/source/arch/arm/boot/dts/omap5.dtsi#L313 scm_wkup_pad_conf: scm_conf@0 { compatible = "syscon", "simple-bus";
Maybe try to rename one of them(for example, rename the second one to "scm_wkup_pad_conf@0").
